`add_server` wrapped `json.loads(args)` in a bare `except` that fell back to `[]`, so an Args value that is not JSON — a bare path, which is what the form's placeholder invites people to type — registered the server and spawned the stdio subprocess with an empty argv. Nothing surfaced the loss: the POST returned 200 and the row persisted with `"args": []`. The route now returns 400 for an unparseable value, and also for valid JSON of the wrong shape: `args=5` reached `StdioServerParameters(args=5)` and raised an unhandled TypeError in the error formatter's `" ".join(...)`. Both form clients mirror the guard instead of leaving the user to read a 400 they cannot see. `settings.js` stops silently defaulting a bad Args value, and `admin.js` gains the same client-side parse check plus a `res.ok` branch so a server-side rejection is not reported as a connection failure. Ported from public `dev` (`9d5c0319`, #6215 upstream, fixing #6211), with its test. The `admin.js` hunks are inert on `lab` — `initMcpForm` early-returns because that form's markup is not in this build — and are carried anyway to keep the two lines from diverging further.
